Claims.

This invention relates to machines for winding wire on armatures, coil cores and the like for example automotive generator armatures and coils, field coils and motor armatures.

One of the objects of this invention is to provide a Winding machine which is under full and accurate control of the operator and subject to actuation in a particularly efiicacious manner to properly wind wires on various types and sizes of armatures, spools and cores for coils, with assurance of producing well balanced, uniform and neat windings in all cases.

Another object of this invention is to provide a winding machine in which a novel means for supporting and rotating an armature or coil to be wound is constructed and arranged to rotate the armature coil under direct control of the operator at all times as to speed and extent of rotation and without requiring use of the operators hands in efiecting such control, whereby the operator may accurately guide wires by hand so that with each revolution of the armature, dual windings will be accurately made thereon.

A further object is the provision in a machine such as described, for quickly and easily adjusting the means for rotating and supporting the armature so that armatures, coils and the like of various shapes and sizes may be wound in the machine.

Another object of this invention is to provide a winding machine such as described which is of simple and inexpensive construction, consists of comparatively few parts, may be inexpensively manufactured, and will be reliable as to performance under hard and continued usage with little or no likelihood of getting out of order or requiring replacement of parts thereof.

Yet another object is to provide a winding machine such as described in which a simple frame structure provides a seat for the operator and a support for spools of wire and the armature rotatin means, from which seat the operator controls the machine with his feet as to rotation of the armature, while at the same time using both hands to feed wires onto the rotating armature, thereby, with a simple construction and arrangement giving the operator full control of the machine so that uniform and balanced windings may be effected.

With the foregoing objects in View, together with such other objects and advantages as may subsequently appear, the invention resides in the parts and in the combination, construction and arrangement of parts hereinafter described and claimed, and illustrated by way of example in the accompanying drawing, in which:

Fig. 1 is a side elevation of a winding machine embodying the present invention;

Fig. 2 is an end elevation of the machine;

Fig. 3 is an enlarged fragmentary elevational view of the armature supporting and rotating means of the machine showing how such means may be adjusted to accommodate the winding of armatures of different sizes; and

Fig. 4 is a sectional view taken on the line 4-4- of Fig. 1 showing the main frame in top plan. a

As shown in the accompanying drawing, one form of winding machine embodying the present invention includes a frame A comprising a narrow elongated top member 5 supported on legs 6 and enlarged as at 1 at one end to provide a seat whereby the operator may sit astride the frame bicycle fashion for openating a pedal drive means B.

Mounted on the top or seat member 5 adjacent the end thereof opposite the enlarged portion 1 is an upright U -shaped member .8 the base 9 of which is secured to member 5 by means of fastenings l0. This U-shaped member acts as a support for the means for supporting and rotating an armature or coil such as the armature C shown in dotted lines in Fig. 3.

As here provided the armature supporting and rotating means includes rotary jaws H and I2 between which the armature is clamped within the space between the opposite arms 8' of the U-shaped member 8.

The jaw H in the form of an arcuate plate is fixed to the inner end of a horizontal shaft I3 'journalled in a bearing l4 formed on the free end of one of the arms 8'. A pulley I5 isfixed on the outer end of the shaft [3 and is driven by means of a belt IS in turn driven by a pulley I! on a crank shaft 18 of the pedal drive means. This crank shaft is journalled in a bearing l9 supported on a cross bracing structure 20 between the legs 6 of the frame A, and terminates in pedals 2| like those on a bicycle whereby the operator sitting astride the member 6 may readily operate the pedals for rotating the pulley l1 thereby driving the belt [6, pulley I 5, shaft 13 and thus rotating the jaw H.

The jaw I2 is mounted so as to rotate freely on an extension 22 at the inner end of a-lead screw 23 which is axially adjustable in screwthreaded engagement with a bearing 24 on the outer end of the other arm 8' of the U-shaped,

member 8. A hand wheel 25 is fixed to the outer end of the lead screw 23 so that on the turning thereof the jaw l2 may be moved into and out of position to cooperate with jaw H for clamping and holding armatures of different sizes subject to rotation when the shaft I3 is rotated.

As here provided the cross bnacing structure 20 affords the support of two reels or spools 26 of wire to be Wound on the armatures. The wire from the spools is led through an opening 21 located in the top or seat member 5 between the point where the operator sits and the upstanding member 8, so that this arrangement affords a wire feeding means subject to being erly guide the wires onto the armature being roerly guide the wires into the armature being rotated by and between the jaws II and 12.

A suitable counter indicator 28 showing the number or revolutions of the armature is operated from the shaft l3 and mounted on the bearing 14 for such shaft, whereby the operator may determine the number of windings made on the armature.

While I have shown and described a specific embodiment of my invention, I do not limit myself to the exact details of construction set forth, and the invention embraces such changes, modifications and equivalents of the parts and their formation and arrangement as come within the purview of the appended claims.

I claim:
